Abstract
The invention provides liquid abradant and a preparation method thereof, which belongs to the technical field of materials. The components in weight percentage of the liquid abradant are: 19 to 21 percent of white alundum powder, 3 to 5 percent of stearic acid, 0.5 to 1.5 percent of beeswax, 10 to 20 percent of oleic acid, 52 to 57 percent of aviation gasoline and 2 to 6 percent of aviation kerosene. The preparation method comprises the following steps of mixing the white alundum powder, the stearic acid, the beeswax, the oleic acid, the aviation gasoline and the aviation kerosene so as to obtain a mixed material; preserving the heat of the mixed material for 10 to 12 hours at a temperature of 200+-5 DEG C, cooling the mixed material to room temperature and preparing the mixed material into the liquid abradant. The liquid abradant with the same volume has the advantages of large processing quantity and short processing time. The liquid abradant prepared by the invention is convenient to use and little in harm to equipment, and has good application prospects.
Description
Technical field
The invention belongs to the aeronautical technology field, particularly a kind of liquid abrasive and preparation method thereof.
Background technology
Domestic stainless milled processed adopts solid abrasive cream or mixed state lapping paste usually at present, and the handled Stainless Steel Watch surface roughness of such abrasive is higher, can not reach the technical requirements of aircraft engine with stainless steel components.The large usage quantity when stainless steel of domestic production is used the abrasive parts processed, cost performance is not high, and the part abrasive is because the composition problem produces infringement for the computer controlled grinding chance simultaneously.
Therefore, exploitation is a kind of can become the problem that presses for solution to the lower liquid abrasive of surfaceness with stainless-steel grinding.
Summary of the invention
At above technical problem, the invention provides a kind of liquid abrasive and preparation method thereof.
Liquid abrasive composition of the present invention is by weight percentage for containing white alundum powder 19～21%, stearic acid 3～5%, beeswax 0.5～1.5%, oleic acid 10～20%, aviation spirit 52～57%, aviation kerosene 2～6%.
The preparation method of liquid abrasive of the present invention is:
1, white alundum powder, stearic acid, beeswax, oleic acid, aviation spirit and aviation kerosene are mixed, blending ratio accounts for 19～21% for white alundum powder by weight percentage, stearic acid accounts for 3～5%, beeswax accounts for 0.5～1.5%, oleic acid accounts for 10～20%, aviation spirit accounts for 52～57%, and aviation kerosene accounts for 2～6%.Placement is no less than 150h under normal temperature condition then, and perhaps insulation is no less than 20h under 40 ℃ of conditions; Obtain mixture.
2, mixture is incubated 10～12h under 200 ± 5 ℃ condition, is cooled to room temperature then, be prepared into liquid abrasive.
Wherein the blending means of various materials is, mixes according to the order of white alundum powder, stearic acid, beeswax, oleic acid, aviation spirit and aviation kerosene, adds stearic acid earlier in white alundum powder, mixes; Add beeswax then, mix; Add oleic acid then, mix; Add oleic acid then, mix; Add aviation spirit then, mix; Add aviation kerosene then, mix.
Liquid abrasive preparation principle of the present invention is: stearic acid is dissolved in the gasoline, can increase the viscosity of gasoline, can reduce the sedimentation speed of abrasive particle simultaneously, and it is more even that abrasive particle is distributed, and stearic acid itself can also play cooling and lubricating and promotes oxidn effect; The aviation spirit evaporation rate is very fast, and is unfavorable to having ground, so add-on should be appropriate; Aviation kerosene can be controlled the evaporation rate of aviation spirit, also can play the effect of cooling and lubricating simultaneously; Beeswax can prevent that fine hair road from appearring in workpiece; Oleic add-on need be controlled in the suitable scope, avoids oleic acid too much workpiece surface to be produced destroying infection, avoids simultaneously that oleic acid is very few can not to work to white alundum powder.
The liquid abrasive of the present invention's preparation is easy to use, little to equipment damage, to stainless steel particularly metallic substance such as 1Cr13,2Cr13 extraordinary grinding effect is arranged, compare with common grinding cream, adopt consubstantiality hydrops body abrasive of the present invention, it is many also to have processing quantity, the advantage that process period is short; Liquid abrasive of the present invention has solved the stainless-steel grinding surfaceness and has been difficult for meeting the requirements of a difficult problem, has a good application prospect.
